Before and After Results
Real score improvements from students in our SAT, AP, ACT and GMAT programs.
Detailed Case Studies
In-depth stories from our students who achieved outstanding results.
I was devastated after my first SAT attempt. The diagnostic test identified my weak points in Reading and Math, and my tutor created a focused plan. In 4 months I went up 240 points and got accepted to UCLA!
After trying other programs, TestPrep Istanbul finally worked. The personalized approach to Data Sufficiency and Critical Reasoning made all the difference. Now I'm doing my MBA at Wharton.
The Science section was my biggest weakness. My tutor taught me efficient data interpretation strategies. The small group format kept my motivation high and I went from 24 to 34!

Our son's school schedule was already very busy. We were happy with both the teaching and the communication.

The AP Exams format felt unnecessarily confusing at first. I was really happy with the lessons.

During the intensive review, we returned to real gaps instead of restarting everything. The feedback I received on AP Comparative Government was clear and practical. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

After my first attempt, I wanted the second round of preparation to feel more organized. Thanks to TestPrep for helping me stay on track.

Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Research into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. Knowing the criteria from the start made the whole task less vague. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.

I was taking AP Seminar at school, but getting used to the exam questions took time. Thank you to the tutor who stayed supportive until the end.

When I started preparing for AP Exams, I wasn't sure what order to study things in. Experiencing the exam format beforehand made test day much less stressful. We focused more on understanding what the problem asked than memorizing formulas. I started tracking the type of mistake, not just the number of questions I completed. Thanks to everyone who supported me.

Breaking AP Environmental Science into smaller pieces worked much better for me. Separating calculation errors from content gaps made revision more useful. I left the exam feeling that I had done what I could.

Anxiety became more visible as the exam got closer. Mistakes became something to work on rather than something to feel bad about.

I chose AP Calculus AB this year and wanted to build a solid base from the beginning. Over time, AP Calculus AB became one of the most organized parts of my AP Exams preparation. I started tracking the type of mistake, not just the number of questions I completed. I started seeing shorter solutions that were easier to check under time pressure. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. We were happy with both the teaching and the communication.

We wanted our child to keep up with the school pace in AP European History. We were able to follow the mock results regularly. The tutor supported regular study, not only the lesson content. Individual lesson time was used around our child's actual needs. It was good to see confidence returning over time. We were happy with both the teaching and the communication.

Keeping up with AP Exams while school was busy was harder than I expected. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I stopped listing facts in essays and started building an actual argument. The preparation felt calmer than I expected.

Keeping up with AP Exams while school was busy was harder than I expected. Questions from other students often helped me as well. Source questions became easier once I noticed how small details affected the mark. My tutor made it easy to ask questions from the first lesson. The group never had more than six students, so it was easy to stay involved. Thank you to the tutor who stayed supportive until the end.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Over time, AP Physics 1 became one of the most organized parts of my AP Exams preparation. We could make the workload lighter during busy weeks at school or university. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. There was no overnight miracle, but the progress was easy to see. It was an intense period, but it was worth it.
